Principal Security Engineer

Reference: 3uihvvhtpoyhc5lqmz5p

We are seeking a Principal Security Engineer to provide technical leadership across the design, implementation and continuous improvement of enterprise security capabilities. You will define and champion security architecture principles, advise engineering and product teams, and help embed secure-by-design practices throughout the development lifecycle. The role will involve assessing complex technology environments, identifying risks, recommending pragmatic controls and ensuring that security solutions support business objectives without unnecessarily limiting innovation.

You will lead initiatives spanning cloud security, application security, infrastructure protection, identity and access management, network security, vulnerability management and incident readiness. Responsibilities will include developing security standards and reference architectures; reviewing designs, code and infrastructure configurations; supporting threat modelling and security testing; improving detection and response capabilities; and contributing to investigations of significant security events. You will also mentor security engineers, influence senior stakeholders, help prioritise the security roadmap and collaborate with audit, risk, privacy and compliance teams to demonstrate effective control operation.

The successful candidate will have substantial experience in a senior security engineering or security architecture role, with a strong record of delivering secure solutions in complex, highly available environments. You will bring practical knowledge of modern cloud platforms, identity technologies, network controls, cryptography, operating systems, software development practices and security tooling. Experience with automation, infrastructure as code, CI/CD security and relevant frameworks such as NIST, ISO 27001 or CIS is desirable. Strong analytical, communication and influencing skills are essential, along with the ability to explain technical risk clearly to both specialist and non-specialist audiences. Professional certifications such as CISSP, CCSP, GIAC or equivalent are advantageous. You should be comfortable working autonomously, making sound decisions in ambiguous situations and balancing strategic thinking with hands-on technical contribution.
